| Abstract: | Lightning strike on power transmission line occurs with certain probability. The line trip-out rate can be reduced by using line surge arresters, the difference in protecting margin is compare by analyzing and calculating the u-t characteristic curve of line arresters with and without gaps, and the technical specification of 110~500 kV line surge arresteris put forward. Insulation coordination regulations and proposals for enhancing protective margin of line arresters are summarized and recommendation for application, installing and maintenance of such arrester is given in consideration of practice in China. |
